UPCOMING: 2011-06-03 09:00 - 2011-06-06 09:00
The refrigeration supply in the ETZ building will be replaced. One server room has to be shutdown completely (ETZ/D/96.2; all compute servers of the institutes). The other server room will get an emergency cooling system (ETZ/F/66). This will, however, not allow the cooling of all currently running servers within that room. Consequently we will shut down as many servers as possible.
Basic services like email, user homes and other network shares, printing and login to Windows or Linux workstations are not expected to be affected by this construction work. In general, if you are not familiar with the server names or service terms below, you should not be affected at all.
These services will not be available during the construction work times:
